But what if you don’t have 48 years of experience with someone to know how to make them happy? Here’s our favorite shortcut: bubbles. Specifically in cocktail form. The mountain of evidence for the happiness brought on by sparkling drinks is everywhere and it’s overwhelming: weddings, New Year’s celebrations, almost every episode of Sex in the City. Think for a moment: Have you ever seen an unhappy person with a Champagne flute? You have not. It may not even be physically possible. In Pépin’s words "a perfect host pleases his or her guests". So get to pleasing people with some sparkling cocktails.
